FRICTION GRAlNlNG-MACHINE.

Specification of Letters Patent.

Patented May 1, 1906.

To all whom it may concern.-

Be it known that we, FRED A. TAYLOR and NATHAN E. FLINT, citizens of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Friction Graining-Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in graining-machines; and the object in view is to produce a simple and efficient means in which a grained surface may be applied to boards, paper, or other articles and comprises various details of construction and combinations and arran ements of parts, which will be hereinafter fufly described and then specifically defined in the appended claims.

Our invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of our grainingmachine. Fi 2 is a top plan view, and Fig. 3 is a sectiona view transversely through the 'machine.

Reference now being had to the details of the drawings by letter, A designates a frame which may be of any suitable construction, and journaled in suitable bearings in the frame is a cylinder B, upon the circumference of which is positioned a design of any kind which it is desired to transfer to the surface of a board or other article, and C is a screw having a hand-wheel C fixed thereto, the inner end of said screw bein fastened to a box D, there being one at eacTr end of the spindle of the cylinder, said screw being provided for the purpose of adjusting said cylinder back and forth in order to regulate the frictional contact between the circumference of said cylinder and the circumference of the cylinder E, which we term the negative cylinder, which is distinguished from the cylinder B, which is called a positive cylinder, and which latter transfers the impression to the circumference of the rintingroller E, which is coated with a pliab l e gelati nous material. The printing-roller E has a s indie E mounted 1n suitable hearings in t e frame of the apparatus and has a conepulley F at one end, to which belted connection may be had for drivin the apparatus.

Mounted over the cylin er B is a rack H, hinged at H to the top of the frame and carrying a series of antifriction-rollers K. The outer end of said rack is provided with screws N, which pass through threaded apertures in the frame of the rack, and said screws are mounted in suitable bearin s upon the frame and provided with hand-wheels N, whereby as the screw is turned in one direction or the other the outer end of said rack may be tilted up or lowered. The hinged end of the rack is fixed to the table 0 and upon which and said rack a board J rests. Directly over the cylinder E is mounted an impression-cylinder I, having a corrugated circumference and adapted to bear against the upper surface of a board or other article to which the graining is to be a plied for the purpose of feeding the board orward and pressing the under surface thereof to receive the graining from the gelatinous surface of the printing-roller E, to which the design has been transferred from the cylinder B. In order to drive the impression-cylinder, we provide a cone-pulley to which belted connections may be had for driving the impression-cylinder at a roper speed. The boxes in which the spind e ends of the impression-cylinder are mounted have screws M swiveled. thereto, said screws passing through threaded bearingsin portions of the frame and are provided with hand-Wheels M at their upper ends, whereby the'im' ression-cylinder may be raised or lowere for the pur ose of increasing or diminishin the frictional contact between the same and the surface of board or other article to be grained.

Directly underneath the cylinder B is a re-- ceptacle Q, in which the graining liquid is placed and in which receptacle the cylinder B turns, so that its surface may be coated. L designates a felt wiper which is fixed to the frame, and its free ed e bears against the circumference of the cyTinder B, whereby portions of the circumference of the c linder B about the design to be transferre may be wiped off.

Positioned underneath the rinting-roller E is a pan or rece tacle P, in w ich a cleansing lkpud is place and R designates two felt ro lers carried by said receptacle P and adapted to bear against the gelatinous coated surface of the printing-roller E for the purpose of cleansing the same as the printing-roller .mg or lowering the screws at the outer end of turns through the liquid in the receptacle P, and T designates a wi er which is fastened to the frame of the mac e and bears against the surface of the printing-roller E, whereby any smearing of h uid upon the surface of the printing-roller L may be cleaned before receiving an impression from the roller B.

The 0 eration'of our apparatus is simple and will be readily understood when taken in connection with the foregoing description and the drawings, and b the provision of the adjustable table it will e observed that the angle at which the board is fed over the printing-roller E may be easily regulated by raisthe rack, and the tension of the corrugated impression-roller may be regulated, whereby the surface of the board or other article may be made to bear against the gelatinous surface of the printing-roller E with varying pressures.

Having thus fully described our invention, What we claim as new, and desire to secure by Letters Patent, is

1. Agraining-machine comprising, in combmation with a frame, a positive adjustable I cylinder adapted to carry a design for the graining, a rinting-roller, an adjustable impression-cy mder, a rack hinged at its inner end intermediate and above said positive cylinder and roller, and means for raising and lowering the outer end of said rack, as set forth; I

2. A graining-machine comprising, in combination with a frame, a horizontally-adjustable ositive cylinder, a printing-roller ournale in the frame of the apparatus, a vertically-adjustable impressionecylinder mount ed above said roller, a rack hinged intermediate and above said positive cylinder and roller, adj usting-screws mounted in threaded apertures in the outer end of said rack and resting upon said frame, as set forth.

In testimony whereof we hereunto aflix our signatures in the presence of two witnesses.
